十六进制转换中文解决思路

try {    String s = "b7c5b4f3"; //思路就是把String转成对应的byte[]数组    byte[] b = new byte[s.length()/2];    for (int i=0, j=0; i<s.length(); i+=2) {        b[j++] = (byte)Integer.parseInt(s.substring(i,i+2), 16);    }    String data = new String(b, "UTF-16BE"); //自己调整编码试试看，如UTF-16LE什么的？    System.out.println(data);} catch (Exception e) {    e.printStackTrace();}

Java code
package com;import java.io.UnsupportedEncodingException;import java.util.Scanner;public class Decoder {public static void main(String[]args){ System.out.println("请输入转换的16进制代码："); Scanner scan=new Scanner(System.in); String getb=scan.nextLine();   String result=decodeString(getb, "GBK");   System.out.println(result);} private static String decodeString(String string, String encoding) {try {byte[]data=string2Bytes(string);return new String(data, encoding);} catch (UnsupportedEncodingException ex) {ex.printStackTrace();}return encoding;} private static byte[] string2Bytes(String string) {int blen=string.length()/2;byte[]data=new byte[blen];for(int i=0;i<blen;i++){String Str=string.substring(2*i,2*(i+1));data[i]=(byte)Integer.parseInt(Str,16);}return data;}}

必须先知道 你这个字符串是什么编码 utf-8
